T0 all whom, 'it may concern.'

Be it known that I, LOUIS Sonnen, a citizen of the Republic of France, and resident of Champigny-SunMarne, Seine, France, have invented new and useful Improvements in Processes of Producing Printed Copies of Kinematographic Films and rthe Like, which improvements aref fully set fort-h in the fol-.

. lowing specification.

A process of producing printed copies oi kinematographic lilms or the like on celluloid or other material is already known.

The process in question is, briefly, as follows 1. The casting on to a plate in relie-t' of gelatin of a solution of `Celluloid or any other plastic material, the said solution being covered, as soon as it is dry, with a plate of Celluloid or any other material; or the application to the said plate in relief of a plate of Celluloid or any other plast-ic materiahwhich, being in either case pressed on hot, produce a counter type in relie-f. 2. The. use of the said counter type in relier" as the movable.

plate of inde-finite length, from which con- -tinuous printing can be effected'v by means of a rotary machine.

This invention hasfirst` of all for its object to provide a method whereby the movable plate just mentioned, can also be 0btai'ned by plaster molding and by countermolding in Celluloid or any other plastic material, by means diierent from that used in the process described; Thus, instead of pouring on the reliefs in gelatin a solution l or celluloid or ofl any other plastic material,

it is possible: either to mold in plaster the reliefs developed in water or mold also in plaster the reliefs obtained by swelling.

For carrying out the counter molding, it is then sullicient topourinto the plaster molding'celluloid or any other plastic material, all. by well known means. It must be pointed out that,vif it is desired to produce afcounter-mold in hot state, in Celluloid or in any other plastic material, with reliefs obtained by swelling, it is necessary toA do the molding iii-plaster in a vacuum.

By the use of plaster moldings, a quick and perfect drying of the plastic material is obtained, the solvent being absorbed very quickly in its bottom portion by the mass of plaster. This does not take place when cellf .c any other plastic material is poured onto a plate made of copper or any other .passage between the two cylinders, the film,

held in contact with a movable plate owing to the tuvo metal. bands, was dried by means of a refrigerating mixture.

In the present invention, the upper metal. band is not employed and two fly wheels are I substituted for the four rolls connected in pairs. The contact is made, and theimpression obtained, by means of a wheel with points, which forms at the same time the pressure and the ink spreading roller. The ink is supplied in the quantity desired by a suitable automatic ink pot arranged in front of the wheel with points.

rfhe way in which the -impression is effected, will be readily understood with the assistance of the accompanying drawing given merelyr by way of example.

The movable 'perforated plate -C, the length of which can vary to suit the subject to be reproduced, is introduced between the pressure roller J and the fly wheel K..

The plate in question, after having been oiled by the automat-ic lubricating device D and the surface thus rendered somewhat greasy, passes under the automatic ink pot or fountain F, which distributes ink over the surface thereof, The inked plate then passes between the roller G and theroller M, together with the l-lm B to be printed, and the impression is thereby produced on the film, the pressure of the rollers serving atv the same time to force the ink from the raised portion of the printing plate-into the hollows thereof, this action being facilitated by virtue of the plate being oily. Therefore the design is really printed by the depressed portions ot' the plate, the in k being all squeezed off of the relief port-ions thereof. The points of the wheel engage .with the periorations of the movable plate, the contact is established with a perfect accuracy and the impression is effected.l The movable plate and the film, carried afterward in the direction of the arrow, pass over the ref frigeratinn mixture contained inthe chamber E, and it is during that passage that the solidilication of the ink (colored gelatin) takes place. On arriving at the ily wheel K, the film is separatedfrom the movable plate C and Winds itself on the drum at B', While the movable plate, continuing its travel on the metal band A, passes in its turn between the fly Wheel K andthe pressure roller J. The device is completed by a roller H guiding the printed lin, and by an automatic wiping device I.

Claim. I

The herein described process of producing; printed copies of kinematograijihic lilnis and the like, which consists in the following steps; first, forming frein the original illm a gelatin plate in relief; second, moldingrom such plate, by means of a matrix of plaster or the like, a flexible printing band of plastic'material such as Celluloid; third, supplying consecutively oil and then a rgclatinous ink to the printing` surface of such band; and, fourth, pressing firmly the inked surface of such printing band against the lilni to be printed, such pressure serving to simultaneously spread the inl: and produce the impression. i

In testimony whereof l4 have signed this specification inthe presence of two subscribing witnesses.
